配合RecyclerView数据为空时会崩溃

[epolar]

设置代码如下

        // 为BGARefreshLayout设置代理
        bgaContent.setDelegate(this);
        // 设置下拉刷新和上拉加载更多的风格     参数1：应用程序上下文，参数2：是否具有上拉加载更多功能
        BGARefreshViewHolder refreshViewHolder = new BGANormalRefreshViewHolder(getActivity(), false);
        // 设置下拉刷新和上拉加载更多的风格
        bgaContent.setRefreshViewHolder(refreshViewHolder);

放在Fragment中使用，配合RecyclerView，数据为空时会直接崩溃，没有数据，不清楚如果有数据是否也会崩溃

失误了，RecyclerView忘了设置LayoutManager了。
使用很方便，感谢分享。希望能保持活跃一直更新.
